Acuflex III Shoulder Rotation Test
This page describes a flexibility test using the Acuflex III shoulder rotation measurement apparatus. Participants lift a bar from behind the back, with the hands as close together as possible. The result is adjusted for biacromial width. There is a similar Shoulder Circumduction where a sliding handle is held in the hands and passed over the head.
purpose: to measure the flexibility of the shoulder region.
equipment required: Acuflex III Shoulder Rotation Device, Shoulder Caliper for measuring biacromial width.
pre-test: Explain the test procedures to the subject. Perform screening of health risks and obtain informed consent. Prepare forms and record basic information such as age, height, body weight, gender, test conditions. Perform an appropriate warm-up. See more details of pre-test procedures.
preparation: Start by measuring the biacromial shoulder width (from acromion to acromion). Place the Acuflex III (or similar stick with measurement scale) behind the back and hold on to the device using a reverse grip (with the thumbs pointing out). Move the Acuflex along so that the index finger of the right hand is located next to the zero point of the scale, where it will stay throughout test. Place the left hand on the other end of the measuring device wherever is comfortable.
procedure: To perform the test stand upright with both arms extended to full length, with elbows locked. Slowly bring the measuring device over the head. Repeat the trial, each time moving the left grip closer, and repeat until you no longer can rotate the shoulders without undue strain or starting to bend the elbows.
scoring: For the final successful trial, take a measurement from the inner edge of the left hand on the side of the little finger. Calculate the final score by subtracting the biacromial width from the best score (shortest distance) between both hands.
target population: shoulder flexibility is important in sports such as golf, swimming and throwing and hitting sports.
advantages: this is a simple test to perform.
disadvantages: you need to purchase a specific apparatus, particularly the biacromial width caliper.
comments: The Acuflex III Bar is constructed of extruded aluminum, and comes complete with instructions and storage box.
